WHEELED INVALID CHAIR.

Application filed .Tu'ne "25, 1925. Serial no. 39,571.

This invention relatesto improvements-in wheeled invalid chairs, and has more par ticul'ar refer'enoeto an improved foot rest or foot supporting means for"charrs of this kind,

safety.

Wheeled invalid chairs now=- in common useare providedwith foot rests which are permanently secured v1na position so as to lie some distanceiabove the floor or ground over whlc'h the=cha1r lsmoved. These foot restsformfan' obstruction whichmakes it quite" difficult for an lnvalid to get into or out of the chair w1th"safety*-as, in'gettm into orout-of theehair, the latterten'ds to tilt or roll away from the user.

A specific object of the invention, therefore, is*to provide a wheeled invalid chair with a foot rest which may be lowered into contact with the ground so that the invalid may readily get into the chair, and to pro vide simple and eflicient means for then 61G? vating the foot rest and holding it elevated in proper position to support the feet of the user when the chair is moved.

With the above general objects in view, and others that will become apparent as the nature of the inventionis better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

*ingback rest' 9"w hich is hinged at its lower f end asatlO to the rear end of the seat mem bGPS'SO that-theinclination Oftllfi'bilfik113st maybe varied, ancl arm' rests 'll have their rear ends hinged as at l2-to the sides of the l ha ck st (9, said {H6111} rests being hinged' at rthen forward ends respectively a to thevup right members which areifhinged inter mediate their ends 1 as i at 14 (Figure 2) to= the:

sides of the seat member 8 at the forward end of the latter. Adjustment of the back rest 9 thus causes inclination of the members 13, and the latter terminate in posts 15 below the pivots 14, which posts depend from the seatmember 8 and usually have the foot rest 16 rigidly attached to the lower end portions thereof. The usual leg 17 is rigid with and depends from the central part of the rear end of the seat member 8 and has a swiveled caster wheel 18 at its lower end adapted to engage the floor or ground for preventing rearward tilting of the chair and facilitating guiding of the same.

In accordance with the present invention the depending posts 15 are provided with longitudinal guide ways 19 upon the inner sides thereof as clearlyshown in Figures 3 and 6, and rigidly secured to the rear corner portions of the foot rest 16 are up wardly projecting arms 20 having laterally projecting portions slidably fitting in the guide ways 19 whereby the foot rest- 16 may be raised or lowered and will be effectively guided when so moved. By reason of the fact that the arms 20 project upwardly, the posts 15 may terminate a distance above the floor or ground and still insure proper association of the foot rest 16 with the posts 15 when said foot rest-is lowered into en gagement with the floor or ground as shown clearly in Figures 1 and 2. When the foot rest is thus lowered into engagement with the floor or ground it is evident that the chair will not readily tilt forwardly and that the foot rest will not present an obstruction such as will prevent the user of the chair to readily get into the same or out of the same.

Attached to the-rear portion of the foot rest 16 is a member 21 having the lower end of a chain 22 secured to the central portion thereof, and the chain 22 passes around suitable guides 23 and 24 to a point adjacent the outer side of one of the arm rests 11 where it is associated with a keeper of the tion of the slot 27 being restricted so that when the chain is slid laterally into this restricted portion it is effectively held against longitudinal movement through the plate 25. Thus, when the chain 22 is pulled upwardly for elevating the foot rest 16 to the desired height, and is then slid later ally to to engage its adjacent portion in the restricted portion of the slot 27, the foot vention will be readily understood and ap-- preciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

In a wheeled invalid chair of the character described, including a seat, a pair of spaced posts at the front of said chair depending beneath the seat and each having a groove in the inner face thereof, a foot rest, a pair of substantially L shaped brackets, eachvhaving one portion thereof secured to the rear edge ofsaid foot rest at one end thereof and having the other portion projecting beyond the adjacent end and engaging in a groove for sliding movement therein, and flexible foot rest operating and supporting means for shifting said foot rest vertically between said legs.

In testimony whereof I affix my signa ture.
